Brook Drumm has created a series of videos that show the assembly process for the basic printrbot. As he produces additional videos and any for the printrbot LC and printrbot+ they can be added here too. Note that once you link to YouTube the videos will chain into a continuous running show. Well, at least the first 15 do this!

This video starts with the assembly of the threaded rod base.
|printrbot LC Video 01
Putting the base together and mounting the z-endstop. Helpful for assembling the printrbot+ too.
|printrbot+ Video 01|
General printrbot LC and printrbot+ differences and assembly techniques.

You want to assemble the X-axis, Video 10/11, before this step so you know how wide to make the base.
|printrbot LC Video 02
Mount z-endstop, printrboard, y-endstop, z motors and feet.
|printrbot LC and + Video 02|
Getting the components oriented correctly and printrboard mounting.

Printer bed and heater design improvements explained. Glass heatbed cover discussed.
|printrbot LC Video 08|
Assemble extruder mount and install the extruder.
||printrbot Video 09
Z-axis end stop installation and printrboard mounting explained. Also showing the y-axis end stop.
|printrbot LC Video 09|
Install z-axis leadscrews, x-axis drive belt.
||printrbot Video 10|
X axis carriage, beginning with the end stop mounting. Note design improvements and retrofitting original design.
I think this is wrong orderwise. I would attached the coupler to the x-motor, such that the geared part is furthest away from the body. Then I would mount the x-motor through the large hole, using three allen screws. Then mount the x-stop switch.

Continuing the x-axis carriage assembly.
||printrbot Video 12|
Carriage assembly with z-axis bearings and leadscrew follower nut installation explained.
||printrbot Video 13|
Assemble the extruder.
